Razorclaw:

Profile: Razorclaw claims to be one of the original Predacons, dating back centuries. He went undercover and infiltrated the Axalon to free Protoform X, who he claims was also an original Predacon named Rampage. Now he is trapped on prehistoric Earth, with no way back to Cybertron. He has left signs that he hopes will be found in the future, so that his fellow "original" Predacons will come to the past to rescue him. Razorclaw will remain motionless for hours, or even days, just to bring his enemies close enough to impale with his claw's protruding cyber-spikes. In robot mode, Razorclaw behaves like a lion, even roaring at Maximals when he strikes. He climbs trees and remains motionless for extended periods. When he strikes, he does so in a quick and sadistic manner. But this battle is not why he is here. He hopes that he can collect enough parts to realign his chronal phase, so he can rejoin his compatriot Rampage. Razorclaw hates all Maximals, but especially Prowl and Grimlock. He claims they are the original Autobots of the same name sent to deter his rescue mission. There has been some speculation that he is actually a clone of the original Predacon Razorclaw.

Abilities: His radar and sonar defeating shell armor allows him to stay cloaked from Maximal sensors underwater as well as on land. His disruptor rifle causes temporary paralysis.

Weaknesses: Razorclaw cares nothing for the battle on prehistoric Earth, unless it means going back to Cybertron. Also, his couplings may become locked if he does not move for long periods.
